Round duct fan Vents VKMts 125 is designed for use in ventilation systems. The fan housing is made of galvanized steel; the motor protection class allows the fan to be used for outdoor installation. The fan is capable of moving air with temperatures from -25°C to +55°C with a maximum capacity of 330 m3/h.
If necessary, it is possible to reduce the fan performance using a speed controller, which can be ordered separately. The fan is used with a network of air ducts with a diameter of 125 mm.

Design
The fan housing is made of galvanized steel. For more convenient connection and use, the fan can be equipped with a power cord with a plug (VKMts…R).
Motor
Single-phase external rotor motors are equipped with a centrifugal impeller with backward-curved blades. The engine is equipped with built-in thermal protection with automatic restart. The use of rolling bearings
in the engine ensures a long service life (40,000 hours). To achieve precise performance, low noise levels and safe fan operation, each turbine undergoes dynamic balancing during assembly. The motor in the fan has a protection class of IP 44.
Speed adjustment
Smooth or step adjustment is carried out using a thyristor or autotransformer. Several fans can be connected to one control device simultaneously, provided that the total power and operating current do not exceed the rated parameters of the controller.
It is possible to use a speed controller (supplied separately) RS-1-300
Installation
Mounting at any angle relative to the fan axis is allowed. Connection to the wall is carried out using mounting brackets, which are included in the delivery set. Power is supplied to the fan through the external terminal box. Electrical connection and installation must be carried out in accordance with the instructions and electrical diagram indicated on the terminal box.
